The English actor has criticised his own “complacent” performance in sixth film, Harry Potter and the Half-Blood Prince, revealing there are moments he is “not as proud of, mistakes other actors get to make in rehearsal rooms or at drama school”.

Radcliffe, who first began playing Potter aged 11, described his famous portrayal of JK Rowling’s hero as “very one-note”, emphasising that he “hates” it.

“My best film is the fifth one (Order of the Phoenix) because I can see a progression,” he told the Mail on Sunday.

“I never liked watching myself on film but I do make myself sit through it,” he said, adding that he thinks the issue stems from “not actually realising I didn’t have to go to my own premieres”.

Radcliffe, who has since earned critical acclaim for a string of stage and screen roles including Horns and Kill Your Darlings, will next be seen playing a medical student in rom-com What If alongside Zoe Kazan.

Earlier this month, he mentioned his interest in taking a seat in the director’s chair at some point in the future because he is “quite good with people”.

“I would love to direct,” Radcliffe told Variety. “I do it in my head when I’m watching other directors direct. The mistake I see even the really good directors make is they assume they are the only creative person on the set.”
